FLUID-PRESSURE GENERATOR.

Specification of Letters Patent.

Patented Mar. 23, 1920.

Application filed July 19, 1919. Serial No. 312,016.

To all whom it may concern:

Be it known that 1, Moses M. KARR, a citizen of the United States, residing at Fair Oaks, in the county of Jasper and State of Indiana, have invented new and useful Improvements in Fluid-Pressure Generators, of which the following is a specification.

This invention relates to- Iluid pressure generators in which a mixed fluid under pressure is generated, the same consisting of steam and the exploded charges of a combustible gas.

The invention has for its object to rovide a simple and eflieient apparatus of tie kind stated, and to this end it consists in a novel combination and arr-z ngement of parts to be hereinafter described and claimed.

In order that the invention may be better understood, reference is had to the accompanying drawing, forming a part of this specification, and in said drawing, a central longitudinal section of the apparatus is shown.

Referring specifically to the drawing, 5 denotes an upright tank adapted to contain a supply of water which is to be heated and converted into steam. The water is heated by injecting into the tank the eX- ploded charges of a combustible gas, whereby a mixed fluid under pressure, is produced, and this fluid pressure may be uti lized to supply a fluid pressure motor of any kind. This motor has not been illustrated as it forms no part of the present invention. Near the top of the tank is an outlet 6 having a suitable connection with the motor to be driven by the mixed fluid under pressure generated in the tank.

In the bottom portion of the tank 5 is lo cated a vertically positioned pump cylinder 7 in which a plunger or piston 8 reciprocates. This plunger is hollow and in its head is a port on which seats a valve 9. The pump plunger is driven from a crank shaft 10 through a connecting rod 11. The pump cylinder is situated over a crank case 10 and its top is closed and has an outlet 12 controlled by a valve 13. This outlet opens into a combustion or explosion chamber 14 located centrally inside the tank 5 and open at its top to discharge into the latter above the water level therein. The upper, outlet end of the combustion chamber has a seat for a valve 15 which is normally held closed by a spring 16. At 17 is indicated a suitable igniting element for firing the charges in the combustion chamber.

In operation, the tank 5 is filled with water up to a level slightly below the outlet end of the comllrustion chamber 14-, and the crank shaft 10 is driven from a suitable source of power. On the downward or suction stroke oi the plunger 8, the valve 9 opens to admit an explosive mixture from a suitable source. 011 the upward stroke of the pump plunger, the valve 9 closes, and the valve 13 opens and allows the explosive charge to pass into the chamber 1% in which it is ignited by the device 17, the valve 13 then closin The force of the explosion opens the valve 15 against the tension oi its sprin 16, and the exploded charge escapes into the tank 5. The water in the tank is therefore subjected to the intense heat of the burning gases, and steam is generated. The steam thus generated mixes with the exploded gases and the mixed fluid, under high pressure is discharged from the outlet 6 for use in any desired manner. Inasmuch as the combustion chamber is immersed in the water in the tank 5, the wall of said chamber assists to heat the water.

The top of the combustion chamber 1 1- is surrounded by a hood 18 which is carried by the valve 15, and enables the water level in the tank 5 to be brought up as high as the valve without danger of leakage of water into the combustion chamber.

The spring 16 is housed in a cylinder 19 which slides in a stuiiing box 20 fitted to the top of the tank 5. The cylinder 19 is 0011- nected to the valve 15 by a stem 21. The top Of the spring 16 is engaged by a plunger 22 carried by a screw stem 2", whereby the tension of the spring may be adjusted. The

screw stem is carried by a suitable support 2 1: mounted on top of the tank The apparatus is shown positioned vertically but it will be understood that this is immaterial, and with slight structural changes the apparatus may be placed in a horizontal position.

At 25 is shown a fuel supply pipe discharging into the crank case 10 and leading from a carburetor or other charge-forming device. For heavy fuels, injection into the chamber 14 by pressure may be made, air only being admitted to the crank case, the operation being similar to that of a Diesel engine.

I claim: for the burning gases into the tank above A fluid-pressure generator comprising a the Water level therein, a spring-seated 10 water tank havin a fluid pressure outlet, a valve associated With said outlet, and a hood combustion cham er in the tank and imaround the valve to isolate the same from 5 mersed in the water therein, means for delivthe Water in the tank.
